Application filed February 3, 1927. Serial No. 165,559.

My invention relates to a can having a friction top closure and its principal objects are to reduce the cost of manufacture of cans of this type and to provide a design of can, the friction top or closure of which can be more readily removed than is the case with cans of ordinary design.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein Fig. 1 is a view in perspective of a can made in accordance with my invention.

Fig. 2 is a plan view of the can, and

Fig. 3 is a fragmentary sectional view on line 3-3 of Fig. 2, with the scale enlarged.

Referring to the drawings, 10 designates the cylindrical body of the can and 11the upper end or head which is flanged at 12 and soldered to the can body, the head being preferably depressed slightly a short distance from the flange so as to provide a reinforcing rib or bead 13 at the edge of the can.

The head 11 is formed with an opening, considerably smaller in diameter than the diameter of the head and located accessibly in the head, the metal of the head being flanged down, as indicated at 14, to provide a friction 'ring for the friction top or cap 15. Preferably the metal around the opening is pressed up slightly to provide a raised seat 14" for the flange 17 of the friction cap which seat has an outwardly sloping shoulder facilitating the prying off of the cap. This expedient of making the opening in the head relatively small andv arranging it close to one edge of the can has advantages over the common design, in which the opening is concentricall'y placed and only slightly less in diameter than the diameter of the head. In the first place, taking into consideration both the head and the friction cap, less metal is used, which though involving but a small difference in a single can, may amount to a good deal where the cans are made in large numbers.

In the second place the cap can be made of small sizes of scrap metal discs procurable at lower cost, in proportion to the gross amount of metal, than discs of the larger.,

sizes.

" In the third place, the friction cap can be more readily removed, due to the elasticity of:

V the head and the fact that one edge of the cap is removed a considerable distance from the corresponding edge of the can. Since the opening in the head is close to and substann tially contiguous with the edge of the head at one point, a pouring rim of minimum width is provided, that is of a Width no greater than the rim around a friction can of ordinary construction.

In the fourth place the cap can be removed with less distortion of cap and can body so that thepossibility of replacement of the cap in 'sealing position is assured.

However, the wide portion of the head, outside lof the friction cap opening, is likely to be too resilient so that it will bend too much under the pressure exerted by the cap- 'ping machine. To overcome this defect, the

wide portion of the head is suitably reinforced, preferably by a straight upwardly projecting rib 16 which extends quite close tothe edge o f the friction cap opening and across the can head, with its ends merging in the circumferential rib or bead 13. This rib is convenient as providing a fulcrum for the instrument used for prying up the friction cap. It rigidifes the head so as to insure a proper frictional grip between the cap 1-5 and the friction ring 14. However, the wide part of the. can head may be bent down a trifle, in spite of the rib, by the capping operation and as a consequence the bead 17 on the cap will stand just a little away from the head on this side, which also tends to makethe removal -of the cap easier, without impairing the frictional grip of the cap aga-inst'the friction ring.

I desire to be understood as intending to cover by patent all modifications of the invention within the scope of the appended claims.

I claim:

1. A metal .can comprising a cylindrical side wall, a head permanently secured to the side wall and formed with a circular filling and pouring opening arranged eccentrically inthe head and substantially contiguous with the edge thereof at one point to provide a pouring rim of minimum width, and a friction cap closure for said opening, the head and closure being formed with friction rings substantially parallel with the side wal'l to provide a drive fit engagement between the closure and head which maintains the closure in place.' y

2. A metal can comprising a cylindrical side wall, a head permanently secured to the side wall and formed with a circular filling and pouring opening arranged eccentrically in the head and substantially contiguous with the edge thereof at one point to provide a pouring rim of minimum width, and a friction cap closure for said openin the head and closure being formed with frlction rings substantially parallel with the side wall to provide a drive it engagement between the closure and head which maintains the closure in place, the wide portion of the head on the opposite side of the opening from the pouring rim being formed with a reinforcing rib at substantially right angles to the diameter of the can head passing through the widest part of said wide portion, the ends of which rib terminate adjacent the edge of the can top to stifen thel head when the friction cap closure is driven into the opening.

3. A metal can comprising a cylindrical sidewall, a head permanently secured tothe side wall and formed with a circular filling and pouring opening arranged eccentrically in the head and substantially contiguous with the edge thereof at one point to provide a pouring rim of minimum width, and a friction cap closure for said openin the head and closure being formed with friction rings substantially parallel with the side wall to provide a drive fit engagement between the closure and head which maintains the closure in place, the Wide portion of the head on the opposite side of the opening from the pourwide portion and the ends of which merge 70 intosaid head.
